I have a bunch of them, mostly stuff from particularly nostalgic periods in my life. I get sentimental so easily haha. I still have this really old fleecy coat I've had since I started school. I'd never give it up even though it's not my style anymore as I mostly wear puffer coats now
The stuff from before I was physically disabled by cars while commuting. Mostly my bicycle racing stuff. My skills matter to me a lot, so like when people appreciate or recall them and ask me stuff about them, even when I do not have the ability to do them any more, I get sentimental.
